Integrating mpeg4 video codec in asterisk

Hi All,

I need help. I intend to integrate mpeg4 codec in asterisk. Does asterisk support any video codecs currently? If yes why it is not in the “codecs” folder?

Moreover can anyone please tell me how a codec is invoked when asterisk receives an incoming call or sends an outgong call?

I shall be very grateful if someone can help me.

Thanks

Zeeshan
